Example Input: Question: In what year did the Kansas City Kings become the Sacramento Kings? Passage:In 1982, at age 22, he became the TV and radio voice of the NBA's Kansas City Kings (now the Sacramento Kings). He then was a basketball announcer for his alma mater, the University of Kansas, for one year, then went on to call games for the NFL's Kansas City Chiefs from 1985–93 after several years hosting and producing surrounding pre-game and post-game programming (coincidentally, current Packers play-by-play voice Wayne Larrivee left the Chiefs position open when he began a thirteen-year run as the voice of the Chicago Bears). Harlan also split time with the University of Missouri (1986–89) calling football and basketball games, and worked as the play-by-play voice of the NBA's Minnesota Timberwolves for nine seasons (1989–98). On the network level, Harlan called NFL football for NBC in 1991, college football for ESPN in 1992–93, NFL for Fox from 1994–97, and joined Turner Sports in 1996 to cover NBA playoff games (he would begin calling games throughout the entire season in 1997, which he continues to do to this day). He began working for CBS in 1998.

Example Input: Question: How many weeks did the single that peaked at number nine spend on the charts? Passage:"Go Girl" was the first single released from the album. It was originally the lead single from the album, but the single achieved minimum success and was later deemed a promo single. However, the single managed to reach the top of the charts in Japan. The album's official lead single, "Never Ever", which features Young Jeezy, was released in the United States in January 2009 and reached a peak of number nine on the U.S. Hot R&B/Hip-Hop Songs. The second single, "Love Sex Magic", featuring Justin Timberlake, became a worldwide hit, peaking within the top ten in twenty countries including the U.S., where it peaked at number ten on the Billboard Hot 100. It went on to be certified platinum in Australia and received a gold accreditation in New Zealand. It received a nomination for "Best Pop Collaboration with Vocals" at the 52nd Annual Grammy Awards and also for Best Choreography in a Video at the 2009 MTV Video Music Awards. "Like A Surgeon" was the fourth single from the album. The song received no promotion and no single cover nor music video was released. However, the song did manage to peak at number fifty-nine on the Hot R&B/Hip-Hop Songs chart from airplay alone. "Work", the final single, achieved moderate success in international markets.

Example Input: Question: In which country did Tzonis studied architecture? Passage:His grandfather was architect Alexandros Tzonis who designed many buildings in Thessaloniki during the Interwar period. Tzonis studied architecture at the National Technical University of Athens (1956 -1961). During the period of his university studies, he was instructed privately in mathematics (Pandelis Rokos) and art (Spyros Papaloukas) meeting regularly with the architect Dimitris Pikionis who was by then retired from teaching. He worked professionally as a stage designer in the theatre and art director in the cinema. (Never on Sunday, 1960 directed by Jules Dassin). In 1961 he moved to the United States as a Ford Fellow, where he pursued his studies at Yale University, briefly in the Drama School and soon after in the School of Art and Architecture under Paul Rudolph, Shadrach Woods, Robert Venturi, and Serge Chermayeff. In 1965, with sponsorship from the Twentieth Century Fund he was appointed fellow at Yale where he carried out pioneering research on Planning and Design Methodology in collaboration with Chermayeff with whom he co-authored The Shape of Community (1972). In 1968 he was invited to teach at the Graduate School of Design at Harvard University by Jerzy Soltan and Josep Lluis Sert appointed assistant professor. There he taught and did advanced research in analytical design methods in association with Walter Isard and Ovadia Salama, receiving outside advice from Anatol Rapaport and Seymour Papert. In collaboration with Ovadia Salama, introducing the newly developed method ELECTRE he worked out a new method for multi-criteria evaluation of architectural projects (1975). In collaboration with Michael Freeman, Etienne de Cointet, and his undergraduate student Robert Berwick, who became later professor of computational linguistics at MIT, he developed a method for design discourse analysis applied to the case of 17th and 18th century texts of French architectural theory, a project funded by the French Government carried out at Harvard and in France (1975).
